COIL SPRING- LOIIGITTTDNAL ARCH SPPQRT Application led. September 8,1930. Serial No. 380,752.

My invention relates to supports for supporting the longitudinal arch ofthe human foot, and more particularly relates to an improvement over myUnited States pat-ent issued June 10, 1930, under Patent Number Oneobject of this invention is to provide a coil spring longitudinal archsupport similar to the one covered in the above mentioned patent, butwhich will require no base between the spring and the insole of a shoe.

This is accomplished by thel provision of a plate extending across andconnected to the largest and lowermost one of the springs coils forassisting in the adjustment of the throw of the spring. And also by theprovision of an elastic section in the top member and surrounding thespring for permitting free action of the spring without its tending toforce the support upwardly away from the insole of a shoe.

With these and other objects in view as will more fully appear, myinvention consists in the construction, novel features, and 25combination of parts hereinafter more fully described, pointed out inthe claims hereto appended, and illustrated in the accompanyingone-sheet drawing, of which:

Figure l is a plan View of the support;

Fig.. 3 is a sectional view taken along the line 3 3 of Fig. l; and,

F ig. 4 is a top view of the spring showing the plate connectingopposite. sides of its largest and lowermost coil.

Like characters of reference designateV like parts in all the figures.

lt is understood that various changes in the form, proportion, size,shape, weight and other details of construction, within the scope oli my'invention may be resorted to without departing from the spirit or broadprinciple offmy invention and without sacriiicing any of the advantagesthereof; and it is also understood that the drawings are to beinterpreted as being illustrative and not restrictive.

l One practical embodiment of the invention as illustrated in thedrawings comprises:

lll

A top member 1, formed to substantially' lit the upper surface of aninsole 2. Beneath the central portion of said top member 1, is provideda substantially conical coiled spring 3 the largest and lowermost coilof 55 which is connected at opposite sides by a plate 4 having a centralpin 5 made integral therewith. Said top member l is bulged upwardly atits central portion to accommodate said spring 3,'and the bulged portionforms a cap 6 `for said spring.

Said cap 6 centrally supports the upper link of a chain 7 by a pin 8.Said chain 7 extends downwardly through said spring 3 and may be hookedover said pin 5 on plate @s 4 for controlling the throw of said spring3.

Said top member 1 and said cap 6 are both preferably constructed ofheavy canvas or leather and are not made integral with each' other, butare connected by a strip 9 ot some 70 resilient material such as rubberor the like which surrounds said cap 6 on three sides. Said strip 9 issecurely` attached at its. outer edge to said top member Land at itsinner edge to said cap 6 by cementing or the like.

In operation the spring 3 resiliently supports said cap 6 upon which thelongitudinal archof the toot rests,whi1e strip 9 Ermits the cap 6 -tomove with the arch of f foot while top member l is held stationary vbythe w remainder of the foot.

Obviously, the invention is susceptible of embodiment in forms otherthan that which is illustrated in the accompanyingdrawings and describedherein, and applicable for uses as and purposes other than as detailed,and l therefore consider as my own all such modifications andadaptations and other uses othe form oi the device herein described asfairly fall Within the scope of my invention. ee

Having thus described -my invention, what is claimed and desired to besecured by Letters Patent, is:

1. A coil spring longitudinal arch support embodying, a substantiallyconical coil an spring, a plate connecting opposite sides of the largestand lowermost coil of said spring,

a transverse pin carried centrally by said plate, a 'cap for saidspring, a chain carried y said cap and adapted to engage said pin B forcontrolling the throat of said spring, a top member spacedly surroundingsaid cap on three sides and adapted to it the insole o a shoe, and aresilient strip connecting said 5 top member and said cap.

2. In a coil spring longitudinal arch support, the combination with asubstantially conical spring for supporting the longitudinal arch of ahuman foot, o" a cap for said spring, a top member spacedly surroundingthree sides of said cap and conforming to the shape of the insole of ashoe, and a resilient strip connecting the adjacent portions of said capand said top member.

3. In a coil spring longitudinal arch support, the combination with asubstantially conical spring for supporting the longitudinal arch of ahuman foot, of a plate extending between and attached to opposite sidesof the largest and lowermost coil o said spring, a cap for the top ofsaid spring, a chain carried by said cap and extending through saidspring to said plate, means carried by said plate orengaging variouslinks of said chain for limiting the throw of said spring, a top memberspacedly surrounding a portion of said cap, and a resilient memberconnecting adjacent portions of said cap and said top member.

4. In a longitudinal arch support the combination with a resilientmember for supporting the arch of a human foot7 a cap for said resilientmember, and a base surrounding a portion of said cap, of an elasticstrip connecting said base and said cap.
